What is the best thing to use now for content applications (reference books, interactive tutorials, tests, etc.)?

Question

Mobile development

I've worked with Adobe AIR for many years, it's really a great tool for creating cross-platform applications. But, in connection with the end of AIR support, I am looking for other tools for creating content applications.
So far I have settled on React and, in particular, on Expo, but I am confused by the lack of some necessary modules (in app purchase for example) and the ability to build iOS applications under Windows (without a virtual machine)
Requirements:
1. Easy to learn for a flasher.
2. Rich UI.
3. The ability to build both for mobile and browser with high performance.
4. Ready-made modules for payment in stores and paypal, authorization and sharing through social networks. networks.
5. Active community, lessons, videos and development prospects for the next 3-5 years.
